【摘要】 针对炼油厂常减压塔顶冷凝系统现存的腐蚀问题,以合成的咪唑啉衍生物为主要组分成功开发了抑制常减压蒸馏装置中HCl-H2S-H2O型腐蚀的水溶性HY型中和缓蚀剂;用经典失重法和电化学法对其进行了缓蚀性能检测,并经实际应用表明,HY型中和缓蚀剂性能优良。更多还原

【Abstract】 For preventing corrosion of the tower overhead of the atmospheric and vacuum distillation in refinery,the water soluble neutralization corrosion inhibitor for the HCl-H 2S-H 2O system corrosion was successfully synthesized with the derivatives of imidazoline.Using the classical weight-loss method and the electrochemical method,the neutralization corrosion inhibitor was tested and evaluated,besides,it was industrial applied in the second atmospheric and vacuum distillation of refinery in Lanzhou Petrochemical Company.The results showed that inhibited effect of HY was good.更多还原
